Think there will be no problem, since I just figured out we can go BACK to Seattle Lighting on Sunday if we absolutely must, even though we also want to do a tandem ride. It took me half a day to think that up and check their website to see they are open on Sunday also. Scary.
So I'm now sure I can get back tomorrow morning in enough time to be there at the 1 pm start, on the bike.
